A conditioning unit (10) of the indirect free cooling type, particularly for conditioning computing centers, of the type comprising:
- an air/air heat exchanger (11), inside which two air flows (12, 13), exchange heat: a primary air flow (12) from and toward an environment to be air-conditioned (14), and a secondary air flow (13), or process flow, drawn from outside,
- first fans (15) for moving the primary air flow (12),
- second fans (16) for moving the secondary air flow (13). The conditioning unit (10) comprises:
- means (17, 18, 19) for detecting temperature and humidity for the primary flow (12) and the secondary flow (13) at the inlet of the conditioning unit (10) and for the primary flow (12) at the delivery toward an environment to be air-conditioned (14),
- means (20, 21) for detecting the flow-rate of the primary flow (12) and of the secondary flow (13),
- means (22, 23) for detecting the electric power absorbed by the first fans (15) and the second fans (16),
- an electronic control and management unit (24) adapted to collect and process the data detected by the detection means (17, 18, 19, 20, 21, 22, 23) and, on the basis of the detected data, adapted to adjust the speed of the first fans (15) and the second fans (16). |
